Mine pale in comparison to most of the others on this thread but my two favorites from 2018 were these:

Both are cards I've wanted for a long while. I got the Bender for my Bender collection and the Musial, well, I've always thought it was a beautiful a card as has been produced.
Here's hoping that Net54 folks have a prosperous and healthy 2019. And you all find that one card that's been on your list the longest.
